Fire stopping for Hildenborough sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Fire stopping in Hildenborough
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Most enquiries involve builders’ foam or ordinary silicone in compartment walls and service penetrations left open after M&E works, on pipe penetrations, joints between fire-resisting walls and floors and cable penetrations.

Fire stopping around Hildenborough: how the place shapes the job
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 24 miles from Hildenborough. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.
Campus buildings at universities such as University of Kent - Tonbridge (2 miles south-east of Hildenborough) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Holiday works at schools like Hildenborough Church of England Primary School often leave service openings to seal before pupils return. Colleges such as West Kent College, 2.3 miles to the south of Hildenborough, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Surface by surface
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement.
Metal pipes
Heat travels along metal pipework. We follow whatever the detail requires and flag anything we can’t match.
Common questions from Hildenborough clients
Is hospital work, at somewhere like Hollanden Park Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can work at a site such as University of Kent - Tonbridge fit around teaching?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Are you members of a third-party fire-stopping installer scheme?
No, and we’d rather be clear about that. Some clients require third-party installer schemes even though the law doesn’t, so it’s worth checking what your contract says. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Can you seal any opening with fire-rated sealant?
No. Each fire-rated sealant is tested for particular services, gap sizes and substrates. Outside that, a different product is needed.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Hildenborough need work, visits can be combined. A fixed quote is given before anything starts.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Agree which areas must stay open
- Let us know about inductions and permits
- Have the specification and drawings to hand
Getting a fixed quote
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.
Advice
Commercial clients in Hildenborough
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Have penetrations checked while they can still be seen
- Look above ceilings when tiles are lifted for other jobs
- Put resealing into every M&E and fit-out package
- Settle who seals which penetrations at the start of a project
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. One visit to deal with every failing joint makes more sense than several trips to a place like Hildenborough, rather than one at a time. Send photographs of each area and we will quote for the lot.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
